如何执行此操作？

您只需在双空格上执行字符串替换，将其替换为单个空格：

如果你想摆脱标签、换行符等，也可以选择这个

Dim text = "My         name      is      " & Environment.NewLine & "    Anas                 Fares"
Dim newText = System.Text.RegularExpressions.Regex.Replace(text, "\s+", " ")

直接转换为：

Dim r As Regex = New Regex("\s{2,}") 'or " {2,}" or "[ ]{2,}", depending on if you want whitespace, or just spaces.
Dim stringWithDoubleSpaces As String = "this  is  a double  spaced  string"
Dim stringWithSingleSpaces As String = r.Replace(stringWithDoubleSpaces, " ")

Dim r As Regex = New Regex("\s{2,}") 'or " {2,}" or "[ ]{2,}", depending on if you want whitespace, or just spaces.
Dim stringWithDoubleSpaces As String = "this  is  a double  spaced  string"
Dim stringWithSingleSpaces As String = r.Replace(stringWithDoubleSpaces, " ")
